1. Hang all political and military confederate leaders.
2. Break up plantations and give land to both poor whites and blacks.
3. Permanent federal troops.
4. Anyone under the age of 12 gets sent to northern boarding schools until they come of age.
Only the second one sounds like a good idea. The rest I could do without. 
Number 3 is exactly the reason the Ku Klux Klan became violent after it was founded.
After enough time there wouldn't be enough members for the KKK since they'd all be dead and after awhile people would stop doing it since people would rather live. And the federal troops would have kept the south mostly equal, instead of the reverse it took. And number four would actually change the south for the good, they'd grow up in the north and not have the same ideas about the north that most in the south do now.
